Video-assisted thoracoscopic resection for intralobar pulmonary sequestration: single modality treatment with video-assisted thoracic surgery

Abstract

of this case. This kind of tumor is usually located in the left upper lobe, as in our case. Because of the presence of thymic tissue in some mediastinal and intrapulmonary teratomas, it has been speculated that these tumors might originate in the thymic tissue. However, the suggestion that early embryogenesis can cause separation or displacement of the thymus can be correct only for tumors found in the anterior mediastinum. The other explanation is that during the initial embryo period, a teratomatous focus in the mediastinum enters that tissue during respiratory growth and settles there. We have not encountered thymic tissue in histologic examinations. Intrapulmonary teratoma is treated by surgical resection. It has been reported that 5 of 18 patients in whom resection was performed died within 1 year. In addition, 4 patients died during the immediate postoperative period. Thus, this kind of tumor causes mortality and morbidity. Lobectomy was successful in our case.
